People who have experienced the death of a partner or family member may be ageing faster than the rest of us, and the more losses you’ve experienced, the faster you seem to age, according to US research. The study found that among US adults aged 33 to 44 years, having experiences of loss was linked to having an older biological age and a faster pace of ageing as measured by changes to DNA known as epigenetic clocks.  They also found that people who had experienced multiple losses by this age were ageing even faster. The researchers say that this accelerated biological ageing may be a key way that experiencing the death of a family member impacts our health later in life.
